Language Families

In addition to Indo-European there are at least fourteen other language families which are the ancestors of modern language around the world.

Eskimo-Aleut	Ural-Altaic
Central American	Hamito-Semitic
South American	Dravidian
Basque	Malayo-Polynesian
Sudanese-Guinean	Sino-Tibetan
Bantu	Japanese-Korean
Khoin	Austro-Asian

Although there is no space here to explain the connections between non-Indo-European languages you could research one or more of these families. Use the David Crystal Encyclopedia of Language which has a detailed index, and use an Internet search engine to find out where the families originated and which languages they gave birth to.

This may lead you to consider one of the great unanswered questions of linguistics - did language emerge in one place and spread throughout the world, or did it develop in several different places simultaneously?
